Specification forming part of Letters Patent No. 110,652, dated January 3, 1871.

To all persons to whom these presents may come Be it known that I, WILLIAM HAYMAN, of Taunton, of the county of Bristol and State of Massachusetts, have invented or discovered a new and useful Composition for the Preservation of the Surfaces ofWoQfi t Qifjjj, 55kg;

to the weather or to sea-water; and I do hereby declare the same to be fully described as follows:

In making the composition, I use goal-gar, forty gallons; naphthaor hgi zine, ten ga ons; silicate of soda, 1880 re 1 we re gallons of .er so as to make a solution of S Baum; lin su tyft gounces; and sulphgtg of Eon, even pounds.

In combining the above ingredients, first thoroughly mix the goal-tar and naphtha or benzinelogether. Next mix the Eng-and the sulphate of ir vogether and with the solu on o so a, after which add to the mixture th Tfi'the cord-tar and fiapliflifir benzine.

In some cases, or for some purposes, a good composition may be made with all the in gredients except the lime; but I prefer to use the latter, as the composition is much improved thereby for general use.

To the composition, w my rd n-insteziwaaretr, a L s wilew may be substituted.

In using the composition, it is to be applied by means of abrush her ways, as paint is generally spread on a surface.

I do not confine my invention to the precise proportions of the ingredients as hereinbefore set forth, as they maybe varied somewhat without producing any material change in the principle or character of the composition.

I claim as my invention- The said composition made of the ingredi' ents and in the manner substantially as hereinbefore explained.

WILLIAM HAYMAN.
